Peptide Comparisons

Head-to-head analysis of popular peptide matchups. Side-by-side dosing, mechanisms, side effects, and recommendations.

Semaglutide vs Tirzepatide

Semaglutide and tirzepatide are the two most prescribed weight management peptides in the world. Both require weekly injections and gradual titration, but they work through different mechanisms and produce different outcomes.

BPC-157 vs TB-500

BPC-157 and TB-500 are the two most popular recovery peptides. They address healing from fundamentally different angles and are frequently combined, but understanding when to use each — or both — matters for optimizing protocols.

CJC-1295 vs Ipamorelin

CJC-1295 and Ipamorelin are the two most commonly used growth hormone peptides. They work through different receptor systems and are synergistic when combined, which is why the CJC + Ipamorelin blend is so popular.

Semaglutide vs Retatrutide

Semaglutide is the proven standard; retatrutide is the next frontier. One is FDA-approved with years of real-world data, the other produced the highest weight loss numbers ever seen in clinical trials but isn't available yet.

Sermorelin vs Tesamorelin

Both are GHRH analogs that stimulate natural growth hormone production, but they differ in potency, regulatory status, and clinical applications.

GHK-Cu vs Epithalon

GHK-Cu and Epithalon are the two most discussed longevity peptides. Both target aging but through completely different mechanisms — one repairs and regenerates tissue, the other targets the molecular clock itself.
